The company’s Tracy warehouse employs more than 3,000 full-time workers, but to fill the influx of holiday orders, Amazon has hired on 3,500 seasonal employees in Northern California, many of whom the company expects to hire in full-time roles after the holidays.

Another way Amazon is tackling the holiday rush is with “Amazon Robotics,” a system of fast-moving robots that lift and transport product bins.

Instead of employees walking to retrieve products, the robots now bring the items to them during the packing process. The robots also enable the warehouse to stock 50 percent more products than sites without the technology.

Take a virtual tour of BART’s ‘Fleet of the Future’

BART rolled out its new “Fleet of the Future” this weekend, offering the public an up-close look at the transit agency’s new test train.

The train cars will replace the agency’s current rolling stock, which began operation more than 40 years ago. The new cars are scheduled to be phased in with the existing fleet in early 2017.

Notable changes include a sleeker design and high-tech features, like automated announcements and six passenger information screens in each car that will provide a system map and real-time arrival information.

The cars have four fewer seats than the current fleet, but offer more space for standing passengers and passengers with luggage. BART also plans to run more cars per train.

The increased capacity is aimed at addressing the agency’s growing ridership, which BART projects to increase to 500,000 in weekday rides in the next five years and one million in the next 40 years.

BART’s goal is to acquire 1,081 new train cars by 2021, which would increase rider capacity by 49 percent.
